Superior moisture, chemical resistance, and mechanical properties make DCB the ideal protective solution for automotive, industrial, and outdoor electronics.
Electrolube, a global expert in electronic chemicals and protective coatings, highlighted the widespread application of DCB, a product in its two-component polyurethane coating series, for protecting critical electronic assemblies against extreme temperatures, humidity, chemicals, and mechanical stress. With its excellent comprehensive protective properties, DCB provides a tough, durable layer for printed circuit boards (PCBs), significantly enhancing the long-term reliability and service life of electronic products.
Electrolube DCB is a two-component (2K), room-temperature cure polyurethane-based conformal coating. Unlike single-component coatings, its two-part system undergoes a chemical reaction upon mixing, forming a cross-linked network that results in a coating with superior mechanical strength, excellent chemical resistance, and a wider operating temperature range. The coating is transparent for board inspection and can be easily applied by brushing, spraying, or dipping.
Comprehensive Environmental Protection: DCB forms a tough, flexible film that effectively blocks moisture, salt spray, dust, fungi, and a wide range of chemicals (e.g., fuels, solvents, cleaning agents), providing protection that meets IPC-CC-830B standards.
Outstanding Mechanical and Thermal Properties: The coating offers good abrasion, scratch, and impact resistance, capable of withstanding vibrations and thermal cycling stresses. It features a broad operating temperature range, maintaining stable performance from low to high temperatures without cracking or delamination.
Excellent Electrical Insulation: DCB provides a high-strength insulating barrier, effectively preventing arcing, leakage current, and short circuits caused by condensation and contamination in high-humidity environments, ensuring safe equipment operation.
Repairability: Unlike some permanent coatings, the polyurethane coating DCB can be removed using dedicated stripping agents, enabling PCB rework, repair, and component replacement, thereby reducing life-cycle costs.
The robust performance of DCB makes it a preferred choice for numerous high-reliability applications:
Automotive Electronics: Ideal for engine control units (ECUs), sensors, battery management systems (BMS), and lighting controllers, which must endure high under-hood temperatures, fluids, and vibrations.
Industrial Electronics: Protects industrial control systems, motor drives, outdoor communication base stations, and power metering equipment against pollutants, temperature fluctuations, and long-term operational stress.
Aerospace and Defense: Used in highly reliable avionics, navigation systems, and military communication equipment.
Consumer Electronics: Applied in high-end outdoor sports equipment, marine electronics, and other areas requiring enhanced durability.
Electrolube is committed to developing high-performance chemical solutions that address real-world engineering challenges. The DCB two-component polyurethane coating exemplifies the company's relentless pursuit of quality and reliability. By providing "armor-like" protection for electronic devices, it empowers customers to develop more durable and reliable next-generation products.
